Abstract

A method of securing an electrical conduit in an electrical conduit fitting including releasably gripping and removably retaining the electrical conduit in the electrical conduit fitting with a conduit retainer disposed in a passage of the electrical conduit fitting prior to press connecting the electrical conduit fitting to the electrical conduit to fixedly attach the electrical conduit fitting to the electrical conduit.

First claim

What is claimed is:

1. A method of securing an electrical conduit in an electrical conduit fitting comprising:
inserting the electrical conduit into an open end of the electrical conduit fitting such that the electrical conduit is disposed in a passage in the electrical conduit fitting;
press fitting the electrical conduit fitting on the electrical conduit to connect the electrical conduit fitting to the electrical conduit, wherein said press fitting the electrical conduit fitting includes radially deforming the electrical conduit fitting to radially compress a press connector disposed in the passage of the electrical conduit fitting on the electrical conduit fitting; and
releasably gripping and removably retaining, before said press fitting the electrical conduit fitting, the electrical conduit in the electrical conduit fitting with a conduit retainer disposed in the passage of the electrical conduit fitting and radially inset from the press connector disposed in the passage of the electrical conduit fitting to enable the electrical conduit to be removed from the electrical conduit fitting before said press fitting the electrical conduit fitting.

2. The method of claim 1 , wherein said releasably gripping and removably retaining the electrical conduit comprises engaging an outer surface of the electrical conduit with the conduit retainer at multiple locations along a length of the electrical conduit.

3. The method of claim 1 , further comprising centering the electrical conduit in the electrical conduit fitting with the conduit retainer.

4. The method of claim 1 , further comprising limiting an insertion depth of the electrical conduit with a stop disposed in the passage of the electrical conduit fitting.

5. The method of claim 1 , wherein said press fitting the electrical conduit fitting includes engaging teeth of the press connector with the electrical conduit to fixedly attach the electrical conduit fitting to the electrical conduit.

6. The method of claim 5 , further comprising sealing between the electrical conduit and the electrical conduit fitting with a gasket disposed in the passage of the electrical conduit fitting.

7. The method of claim 6 , further comprising separating the gasket from the press connector with a separator in the passage of the electrical conduit fitting.

8. The method of claim 1 , wherein the electrical conduit comprises a first electrical conduit and the open end of the electrical conduit fitting comprises a first open end, the method further comprising:
inserting a second electrical conduit into a second open end of the electrical conduit fitting such that the second electrical conduit is disposed in the passage in the electrical conduit fitting; and
press fitting the second electrical conduit fitting on the second electrical conduit to connect the second electrical conduit fitting to the second electrical conduit, wherein said press fitting the second electrical conduit fitting includes radially deforming the second electrical conduit fitting to radially compress a second press connector disposed in the passage of the electrical conduit fitting on the second electrical conduit fitting.

9. The method of claim 8 , further comprising releasably gripping and removably retaining, before said press fitting the second electrical conduit fitting, the second electrical conduit in the electrical conduit fitting with a second conduit retainer disposed in the passage of the electrical conduit fitting and radially inset from the second press connector disposed in the passage of the electrical conduit fitting.

10. The method of claim 9 , further comprising centering the second electrical conduit in the electrical conduit fitting with the second conduit retainer.

11. The method of claim 9 , further comprising limiting an insertion depth of the second electrical conduit with a stop disposed in the passage of the electrical conduit fitting.

12. The method of claim 1 , wherein said releasably gripping and removably retaining the electrical conduit comprises engaging an outer surface of the electrical conduit with a resiliently deformable detent of the conduit retainer.
